Eurosceptic firebrand and self-styled scourge of the establishment, Nigel Farage makes his final speech as Ukip leader this morning (16 September), ahead of his successor being unveiled. The 52-year-old said he wanted to have his life back after his political dreams came true and the UK voted to leave the EU in a 23 June referendum.

Farage, a married father of four, had infamously "un-resigned" after he failed to win the South Thanet seat at the 2015 general election.

Douglas Carswell, Ukip's sole MP, has failed to endorse a candidate. Ukip's next leader will inherit a party which won more than 3.8 million votes at the general election, has 488 councillors, 22 MEPs, six Welsh Assembly members and two London Assembly members.

But Ukip's core goal – of leaving the EU – has been achieved and new Prime Minister Theresa May has promised to lift the ban on new grammar schools in England, another one of Ukip's flagship policies.

The anti-immigration party has also been hit with high-profile defections to the Tories, with former media chief Alexandra Phillips and ex-party director Steve Stanbury jumping ship.

Farage, who quit the metal markets to become a founding member of Ukip in 1993, is expected to make his address to the party faithful around 11:45 BST.

The party's new leader will be unveiled around 13:30. You can watch the event live here and on Sky News, dependent on timings.
